Eyeglasses which have removable and replaceable lenses to meet individual vision requirements with respect to focal length and strength. In one embodiment, the lenses are slidably and removably mounted to a rod-like holding element. The position of the lenses relative to one another can be changed by sliding the lenses along the holding element. This allows the eyeglasses to accommodate differences in the eye spacing among people. The lenses can also be removed and replaced should an individual desire or need lenses of different focal lengths or strengths.
